We have carpet over concrete and rainy season (and a few overflowed tubs and one … Backed of septic system … I’ve seen said issue. Indeed it is mystifying. I have a possible answer that comes with corresponding emotion of true/this is fact. Ignore carpet. You have water on the concrete. Huge puddles. Carpet only shows initial boot print at first but the puddle of water was already present in other nearby areas under the carpet – only revealed later. Fibers in carpet and towel alike hold surprisingly less water than a concrete floor can. Corn starch holds more, but may be too messy for cleanup. Unfinished concrete is also an excellent sponge with many tiny hiding holes for water. Porous. Caves. Carpet has caves too but not as many. Also if you have carpet padding underneath… That’s a SPONGE of HUGE surface area. Yet … I believe most of the water was on the concrete itself. Passed through quickly but was slower on it’s return back up to the surface where you can see it and a towel could pick perhaps a 1/2 cup of water at a time off of. I measured a few years ago. (Found flax seed a perfect temporary damn maker for broken AC drip tray – glutinous but amazing. I experimented with many things to soak up/ contain water.. Many surprises. Corn starch also a winner. Messy too. But this was on concrete/painted latex. Different scenario altogether. Water on a balloon vs water on a really hard sponge. (Unfin conc). Thus ends brain dump. Thoughts welcomed.
Humans are lucky with our silicon skin producing silicon oils. Makes us nice and waterproof. Poor concrete gets soaked. Even latex (rubber/paint/a balloon stretched over surfaces) isn’t as good as our silicon skin. That’s why we wash up so easily. Paint doesn’t stick to silicon caulking but it does to concrete, which is fluffy. Interesting to note: Portland cement is made by hydration. It hardens when wet.
Humidifiers help as well. We’ve had to use them.
Also concrete isn’t always level. Usually isn’t. So – puddles. And… sideways water movement across carpet padding/spreading across cement floor itself.
Oh, and fans pointed at the floor. Disaster cleanup uses lots of fans to dry up flooded houses. But shopvacs are definitely the best.
I’ll check philosophy forum to get more info – after coffee. need coffee
Thank you for the tag. And yes, as much as I pretended to have answers, they’re merely speculations and pretention on my part. (pretention – pretend – cool, didn’t notice obvious connection between words lol).
So yeah, I was pretending to have a clue. It’s one of those head-scratchers. “How did the water get here?”
Water is an amazing substance. A mysterious leak in a roof can have a source that’s no where near the drip spot… and the cause may be entirely invisible unless the roof (concave porch roof – giant bucket when gutters are slow) – is filled with water. THEN the mysterious hole appears… but still.. far away from the drip… a lifted up piece of caulking a millimeter tall… a stray tiny bug gets stuck under a bit of loosening tar sealant making a temporary valve that washes away upon later inspection… and reseals itself partially upon being heated by the sun… or maybe the heavy water moves the whole porch a tiny big away from the rest of the house.. but then it shifts back when it drains…
we never get enough facts to solve some problems. Just head-scratchers.
ah I was reading things out of order.
Is the crack one built-in to help the house deal with expansion and contraction from the cold… or for drainage? My basement in NJ had a thin crack running all around the outer walls. For winter expansion and also to allow drainage in case of flooding.
This would occasionally result in flooded basement during heavy rains… as the same thing that drains… also works both ways.
Houses rarely are safely completely sealed from the surroundings. Without some give and take from the surrounding area, a flood can make a house float away. Water that’s allowed to “get inside” on occasion can help anchor the house in place… part of the local … ecosystem? (not sure if right word).
Think of a plastic bowl in mud. Push the bowl down in the mud.
Now think of a spaghetti strainer in mud. Push the strainer down in the mud.
So be sure crack isn’t intentional.. lest your house decides to go sliding one day…. or floating..
Vapor barriers are also something tricky in construction. My knowledge here is also just a limited, but I will pretentiously pretend to have a plausable story anyway.
Vapor barriers (plastic sheets) put on in incorrectly can end up rotting wood, causing mold problems in concrete, etc. Has something to do with the difference in humidity (water levels – water again) – between inside and outside of house.. and the whole “sweating glass in the summertime” effect.
Condensation and whatnot.
Water is amazing. Destroys everything in its path eventually. We drink it. It’s healthy. Amazing stuff.
THIS COMMENT IS NOT ABOUT THE NAIL.
CJ Love the story of your grandma here. See: “It’s Not About the Nail” video for reference material.[I had great difficulty explaining the concept to somebody just yesterday – well three – three grown men who _should_ understand why it’s not about the nail by now… but I forget the power of societal dichotomies between male/female [as opposed to biological-in-origin dichotomy, which is more of a spectrum.. but anyway]
Anyway…yeah. If you said, “This is the problem, not that”, she’d get upset I mean, yes, she’s trying to solve your water problem too, but that’s not her main concern. She wants to be your grandma and all that goes along with it. It includes such things as boots. You are a wise grandson indeed, and she, a wise grandma.
Those three guys I was arguing with on the youtube forum who were calling the woman “stupid”, didn’t understand what she was really all about. [and, I wouldn’t be surprised if they had poor relationships with their mothers and/or grandmothers.. but that’s just speculation on my part – generalizing from a limited set of data]
https://www.youtube.com/watch?v=-4EDhdAHrOg – this only seems to be digression. It’s not. But I’ll go back to our regularly scheduled leaky floor program after this brief related message.
